-## 255.1.0
-
-### New features
-
-* The client localisation manager now supports hot-reloading ftl files. 
-* TransformSystem can now raise `GridUidChangedEvent` and `MapUidChangedEvent` when a entity's grid or map changes. This event is only raised if the `ExtraTransformEvents` metadata flag is enabled.
-
-### Bugfixes
-
-* Fixed a server crash due to a `NullReferenceException` in PVS system when a player's local entity is also one of their view subscriptions.  
-* Fix CompileRobustXamlTask for benchmarks.
-* .ftl files will now hot reload.
-* Fix placementmanager sometimes not clearing.
-
-### Other
-
-* Container events are now documented.
-
-
-## 255.0.0
-
-### Breaking changes
-
-* `RobustIntegrationTest` now pools server/client instances by default. If a custom settings class is provided, it will still disable pooling unless explicitly enabled.
-  * Server/Client instances that are returned to the pool should be disconnected. This might require you to update some tests.
-  * Pooled instances also require you to use `RobustIntegrationTest` methods like `WaitPost()` to ensure the correct thread is used.
-
-### Bugfixes
-
-* Fix `EntityDeserializer` improperly setting entity lifestages when loading a post-mapinit map.
-* Fix `EntityManager.PredictedDeleteEntity()` not deleting pure client-side entities.
-* Fix grid fixtures using a locale dependent id. This could cause some clients to crash/freeze when connected to a server with a different locale.
-
-### Other
-
-* Add logic to block cycles in master MIDI renderers, which could otherwise cause client freezes.
-
-
-## 254.1.0
-
-### New features
-
-* Add CC ND licences to the RGA validator.
-* Add entity spawn prediction and entity deletion prediction. This is currently limited as you are unable to predict interactions with these entities. These are done via the new methods prefixed with "Predicted". You can also manually flag an entity as a predicted spawn with the `FlagPredicted` method which will clean it up when prediction is reset.
-
-### Bugfixes
-
-* Fix tile edge rendering for neighbor tiles being the same priority.
-
-### Other
-
-* Fix SpawnAttachedTo's system proxy method not the rotation arg like EntityManager.
-
-
-## 254.0.0
-
-### Breaking changes
-
-* Yaml mappings/dictionaries now only support string keys instead of generic nodes
-  * Several MappingDataNode method arguments or return values now use strings instead of a DataNode object
-  * The MappingDataNode class has various helper methods that still accept a ValueDataNode, but these methods are marked as obsolete and may be removed in the future.
-  * yaml validators should use `MappingDataNode.GetKeyNode()` when validating mapping keys, so that errors can print node start & end information
-* ValueTuple yaml serialization has changed
-  * Previously they would get serialized into a single mapping with one entry (i.e., `{foo : bar }`)
-  * Now they serialize into a sequence (i.e., `[foo, bar]`)
-  * The ValueTuple serializer will still try to read mappings, but due to the MappingDataNode this may fail if the previously serialized "key" can't be read as a simple string
-
-### New features
-
-* Add cvar to disable tile edges.
-* Add GetContainingContainers method to ContainerSystem to recursively get containers upwards on an entity.
-
-### Internal
-
-* Make component lifecycle methods use generics.
-
-
-## 253.0.0
-
-### New features
-
-* Add a new `SerializationManager.PushComposition()` overload that takes in a single parent instead of an array of parents.
-* `BoundUserInterfaceMessageAttempt` once again gets raised as a broadcast event, in addition to being directed.
-  * This effectively reverts the breaking part of the changes made in v252.0.0
-* Fix CreateDistanceJoint using an int instead of a float for minimum distance.
-
-### Bugfixes
-
-* Fix deferred component removal not setting the component's life stage to `ComponentLifeStage.Stopped` if the component has not yet been initialised.
-* Fix some `EntitySystem.Resolve()` overloads not respecting the optional `logMissing` argument.
-* Fix screen-space overlays not being useable without first initializing/starting entity manager & systems
-* ItemList is now significantly optimized. VV's `AddComponent` window in particular should be much faster.
-* Fix some more MapValidator fields.
-* Fix popup text overflowing the sides of the screen.
-* Improve location reporting for non-writeable datafields via analyzer.
-
-### Other
-
-* TestPoint now uses generics rather than IPhysShape directly.
-
-
-## 252.0.0
-
-### Breaking changes
-
-* BoundUserInterfaceMessageAttempt is raised directed against entities and no longer broadcast.
-
-
-## 251.0.0
-
-### Breaking changes
-
-* Localization is now separate between client and server and is handled via cvar.
-* Contacting entities no longer can be disabled for CollisionWake to avoid destroying the contacts unnecessarily.
-
-### New features
-
-* Added `DirectionExtensions.AllDirections`, which contains a list of all `Direction`s for easy enumeration.
-* Add ForbidLiteralAttribute.
-* Log late MsgEntity again.
-* Show entity name in `physics shapeinfo` output.
-* Make SubscribeLocalEvent not require EntityEventArgs.
-* Add autocomplete to `tp` command.
-* Add button to jump to live chat when scrolled up.
-* Add autocomplete to `savemap` and `savegrid`.
-
-### Bugfixes
-
-* Fix velocity not re-applying correctly on re-parenting.
-* Fix Equatable on FormattedMessage.
-* Fix SharedTransformSystem methods logging errors on resolves.
-
-### Other
-
-* Significantly optimized tile edge rendering.
-
-### Internal
-
-* Remove duplicate GetMassData method.
-* Inline manifold points for physics.
-
-
-## 250.0.0
-
-### Breaking changes
-
-* The default shader now interprets negative color modulation as a flag that indicates that the light map should be ignored.
-  * This can be used to avoid having to change the light map texture, thus reducing draw batches.
-  * Sprite layers that are set to use the "unshaded" shader prototype now use this.
-  * Any fragment shaders that previously the `VtxModulate` colour modulation variable should instead use the new `MODULATE` variable, as the former may now contain negative values.
-
-### New features
-
-* Add OtherBody API to contacts.
-* Make FormattedMessages Equatable.
-* AnimationCompletionEvent now has the AnimationPlayerComponent.
-* Add entity description as a tooltip on the entity spawn panel.
-
-### Bugfixes
-
-* Fix serialization source generator breaking if a class has two partial locations.
-* Fix map saving throwing a `DirectoryNotFoundException` when given a path with a non-existent directory. Now it once again creates any missing directories.
-* Fix map loading taking a significant time due to MappingDataNode.Equals calls being slow.
-
-### Other
-
-* Add Pure to some Angle methods.
-
-### Internal
-
-* Cleanup some warnings in classes.
-
-
-## 249.0.0
-
-### Breaking changes
-
-* Layer is now read-only on VisibilityComponent and isn't serialized.
-
-### New features
-
-* Added a debug overlay for the linear and angular velocity of all entities on the screen. Use the `showvel` and `showangvel` commands to toggle it.
-* Add a GetWorldManifold overload that doesn't require a span of points.
-* Added a GetVisMaskEvent. Calling `RefreshVisibilityMask` will raise it and subscribers can update the vismask via the event rather than subscribers having to each manually try and handle the vismask directly.
-
-### Bugfixes
-
-* `BoxContainer` no longer causes stretching children to go below their minimum size.
-* Fix lights on other grids getting clipped due to ignoring the light range cvar.
-* Fix the `showvelocities` command.
-* Fix the DirtyFields overload not being sandbox safe for content.
-
-### Internal
-
-* Polygon vertices are now inlined with FixedArray8 and a separate SlimPolygon using FixedArray4 for hot paths rather than using pooled arrays.
-
-
-## 248.0.2
-
-### Bugfixes
-
-* Don't throw in overlay rendering if MapUid not found.
-
-### Internal
-
-* Reduce EntityManager.IsDefault allocations.
-
-
-## 248.0.1
-
-### Bugfixes
-
-* Bump ImageSharp version.
-* Fix instances of NaN gain for audio where a negative-infinity value is being used for volume.
-
-
-## 248.0.0
-
-### Breaking changes
-
-* Use `Entity<MapGridComponent>` for TileChangedEvent instead of EntityUid.
-* Audio files are no longer tempo perfect when being played if the offset is small. At some point in the future an AudioParams bool is likely to be added to enforce this.
-* MoveProxy method args got changed in the B2DynamicTree update.
-* ResPath will now assert in debug if you pass in an invalid path containing the non-standardized directory separator.
-
-### New features
-
-* Added a new `MapLoaderSystem.TryLoadGrid()` override that loads a grid onto a newly created map.
-* Added a CVar for the endbuffer for audio. If an audio file will play below this length (for PVS reasons) it will be ignored.
-* Added Regex.Count + StringBuilder.Chars setter to the sandbox.
-* Added a public API for PhysicsHull.
-* Made MapLoader log more helpful.
-* Add TryLoadGrid override that also creates a map at the same time.
-* Updated B2Dynamictree to the latest Box2D V3 version.
-* Added SetItems to ItemList control to set items without removing the existing ones.
-* Shaders, textures, and audio will now hot reload automatically to varying degrees. Also added IReloadManager to handle watching for file-system changes and relaying events.
-* Wrap BUI disposes in a try-catch in case of exceptions.
-
-
-### Bugfixes
-
-* Fix some instances of invalid PlaybackPositions being set.
-* Play audio from the start of a file if it's only just come into PVS range / had its state handled.
-* Fix TryCopyComponents.
-* Use shell.WriteError if TryLoad fails for mapping commands.
-* Fix UI control position saving causing exceptions where the entity is cleaned-up alongside a state change.
-* Fix Map NetId completions.
-* Fix some ResPath calls using the wrong paths.
-
-### Internal
-
-* Remove some unused local variables and the associated warnings.
-
-
-## 247.2.0
-
-### New features
-
-* Added functions for copying components to `IEntityManager` and `EntitySystem`.
-* Sound played from sound collections is now sent as "collection ID + index" over the network instead of the final filename.
-  * This enables integration of future accessibility systems.
-  * Added a new `ResolvedSoundSpecifier` to represent played sounds. Methods that previously took a filename now take a `ResolvedSoundSpecifier`, with an implicit cast from string being interpreted as a raw filename.
-* `VisibilitySystem` has been made accessible to shared as `SharedVisibilitySystem`.
-* `ScrollContainer` now has properties exposing `Value` and `ValueTarget` on its internal scroll bars.
-
-### Bugfixes
-
-* Fix prototype hot reload crashing when adding a new component already exists on an entity.
-* Fix maps failing to save in some cases related to tilemap IDs.
-* Fix `Regex.Escape(string)` not being available in sandbox.
-* Prototypes that parent themselves directly won't cause the game to hang on an infinite loop anymore.
-* Fixed disconnecting during a connection attempt leaving the client stuck in a phantom state.
-
-### Internal
-
-* More warning cleanup.
-
-## 247.1.0
-
-### New features
-
-* Added support for `Color[]` shader uniforms
-* Added optional minimumDistance parameter to `SharedJointSystem.CreateDistanceJoint()`
-
-### Bugfixes
-
-* Fixed `EntitySystem.DirtyFields()` not actually marking fields as dirty.
-
-### Other
-
-* Updated the Yamale map file format validator to support v7 map/grid files.
-
-
-## 247.0.0
-
-### Breaking changes
-
-* `ITileDefinitionManager.AssignAlias` and general tile alias functionality has been removed. `TileAliasPrototype` still exist, but are only used during entity deserialization.
-* `IMapManager.AddUninitializedMap` has been removed. Use the map-init options on `CreateMap()` instead.
-* Re-using a MapId will now log a warning. This may cause some integration tests to fail if they are configured to fail
-  when warnings are logged.
-* The minimum supported map format / version has been increased from 2 to 3.
-* The server-side `MapLoaderSystem` and associated classes & structs has been moved to `Robust.Shared`, and has been significantly modified.
-  * The `TryLoad` and `Save` methods have been replaced with grid, map, generic entity variants. I.e, `SaveGrid`, `SaveMap`, and `SaveEntities`.
-  * Most of the serialization logic and methods have been moved out of `MapLoaderSystem` and into new `EntitySerializer`
-    and `EntityDeserializer` classes, which also replace the old `MapSerializationContext`.
-  * The `MapLoadOptions` class has been split into `MapLoadOptions`, `SerializationOptions`, and `DeserializationOptions`
-    structs.
-* The interaction between PVS overrides and visibility masks / layers have changed:
-  * Any forced entities (i.e., `PvsOverrideSystem.AddForceSend()`) now ignore visibility masks.
-  * Any global & session overrides (`PvsOverrideSystem.AddGlobalOverride()` & `PvsOverrideSystem.AddSessionOverride()`) now respect visibility masks.
-  * Entities added via the `ExpandPvsEvent` respect visibility masks.
-  * The mask used for any global/session overrides can be modified via `ExpandPvsEvent.Mask`.
-* Toolshed Changes:
-  * The signature of Toolshed type parsers have changed. Instead of taking in an optional command argument name string, they now take in a `CommandArgument` struct.
-  * Toolshed commands can no longer contain a '|', as this symbol is now used for explicitly piping the output of one command to another. command pipes. The existing `|` and '|~' commands have been renamed to `bitor` and `bitnotor`.
-  * Semicolon terminated command blocks in toolshed commands no longer return anything. I.e., `i { i 2 ; }` is no longer a valid command, as the block has no return value.
-
-### New features
-
-* The current map format/version has increased from 6 to 7 and now contains more information to try support serialization of maps with null-space entities and full game saves.
-* `IEntitySystemManager` now provides access to the system `IDependencyCollection`.
-* Toolshed commands now support optional and `params T[]` arguments. optional / variable length commands can be terminated using ';' or '|'.
-
-### Bugfixes
-
-* Fixed entity deserialization for components with a data fields that have a AlwaysPushInheritance Attribute
-* Audio entities attached to invisible / masked entities should no longer be able to temporarily make those entities visible to all players.
-* The map-like Toolshed commands now work when a collection is piped in.
-* Fixed a bug in toolshed that could cause it to preferentially use the incorrect command implementation.
-  * E.g., passing a concrete enumerable type would previously use the command implementation that takes in an unconstrained generic parameter `T` instead of a dedicated `IEnumeerable<T>` implementation.
-
-### Other
-
-* `MapChangedEvent` has been marked as obsolete, and should be replaced with `MapCreatedEvent` and `MapRemovedEvent.
-* The default auto-completion hint for Toolshed commands have been changed and somewhat standardized. Most parsers should now generate a hint of the form:
-  * `<name (Type)>` for mandatory arguments
-  * `[name (Type)]` for optional arguments
-  * `[name (Type)]...` for variable length arguments (i.e., for `params T[]`)
-
-
-## 246.0.0
-
-### Breaking changes
-
-* The fixes to renderer state may have inadvertantly broken some rendering code that relied upon the old behavior.
-* TileRenderFlag has been removed and now it's just a byte flag on the tile for content usage.
-
-### New features
-
-* Add BeforeLighting overlay draw space for overlays that need to draw directly to lighting and want to do it immediately beforehand.
-* Change BlurLights to BlurRenderTarget and make it public for content usage.
-* Add ContentFlag to tiles for content-flag usage.
-* Add a basic mix shader for doing canvas blends.
-* Add GetClearColorEvent for content to override the clear color behavior.
-
-### Bugfixes
-
-* Fix pushing renderer state not restoring stencil status, blend status, queued shader instance scissor state.
-
-
-## 245.1.0
-
-### New features
-
-* Add more info to the AnchorEntity debug message.
-* Make ParseObject public where it will parse a supplied Type and string into the specified object.
-

-* Revert `BaseWindow` OnClose ordering due to prior reliance upon the ordering.
-
-
-## 243.0.0
-
-### Breaking changes
-
-* RemoveChild is called after OnClose for BaseWindow.
-
-### New features
-
-* BUIs now have their positions saved when closed and re-used when opened when using the `CreateWindow<T>` helper or via manually registering it via RegisterControl.
-
-### Other
-
-* Ensure grid fixtures get updated in client state handling even if exceptions occur.
-
-
-## 242.0.1
-

-
-### Internal
-
-* Avoid normalizing angles constructed from vectors.
-
-
-## 242.0.0
-
-### Breaking changes
-
-* The order in which the client initialises networked entities has changed. It will now always apply component states, initialise, and start an entity's parent before processing any children. This might break anything that was relying on the old behaviour where all component states were applied before any entities were initialised & started.
-* `IClydeViewport` overlay rendering methods now take in an `IRenderHandle` instead of a world/screen handle.
-* The `OverlayDrawArgs` struct now has an internal constructor.
-
-### New features
-
-* Controls can now be manually restyled via `Control.InvalidateStyleSheet()` and `Control.DoStyleUpdate()`

-* `OverlayDrawArgs` struct now has an `IRenderHandle` field such that overlays can use the new `RenderControl()` methods.
-* TileSpawnWindow will now take focus when opened.
-
-### Bugfixes
-
-* Fixed a client-side bug where `TransformComponent.GridUid` does not get set properly when an existing entity is attached to a new entity outside of the player's PVS range.
-* EntityPrototypeView will only create entities when it's on the UI tree and not when the prototype is set.
-* Make CollisionWake not log errors if it can't resolve.
-
-### Other
-
-* Replace IPhysShape API with generics on IMapManager and EntityLookupSystem.
-
-### Internal
-
-* Significantly reduce allocations for Box2 / Box2Rotated queries.
-
-
-## 241.0.0
-
-### Breaking changes
-
-* Remove DeferredClose from BUIs.
-
-### New features
-
-* Added `EntityManager.DirtyFields()`, which allows components with delta states to simultaneously mark several fields as dirty at the same time.
-* Add `CloserUserUIs<T>` to close keys of a specific key.
-
-### Bugfixes
-
-* Fixed `RaisePredictiveEvent()` not properly re-raising events during prediction for event handlers that did not take an `EntitySessionEventArgs` argument.
-* BUI openings are now deferred to avoid having slight desync between deferred closes and opens occurring in the same tick.
-
-
-## 240.1.2
-
-
-## 240.1.1
-
-### Bugfixes
-
-* Fixed one of the `IOverlayManager.RemoveOverlay` overrides not fully removing the overlay.
-
-
-## 240.1.0
-
-### New features
-
-* Added an `AsNullable` extension method for converting an `Entity<T>` into an `Entity<T?>`
-
-### Bugfixes
-
-* Fixed an exception in `PhysicsSystem.DestroyContacts()` that could result in entities getting stuck with broken physics.
-
-### Other
-
-* `GamePrototypeLoadManager` will now send all uploaded prototypes to connecting players in a single `GamePrototypeLoadMessage`, as opposed to one message per upload.
-
-
-## 240.0.1
-
-### Bugfixes
-
-* Fixed `SharedBroadphaseSystem.GetBroadphases()` not returning the map itself, which was causing physics to not work properly off-grid.
-
-
-## 240.0.0
-
-### Breaking changes
-
-* `ComponentRegistry` no longer implements `ISerializationContext`
-* Tickrate values are now `ushort`, allowing them to go up to 65535.
-
-### New features
-
-* Console completion options now have new flags for preventing suggestions from being escaped or quoted.
-* Added `ILocalizationManager.HasCulture()`.
-* Static `EntProtoId<T>` fields are now validated to exist.
-
-### Bugfixes
-
-* Fixed a state handling bug in replays, which was causing exceptions to be thrown when applying delta states.
-
-### Other
-
-* Reduced amount of `DynamicMethod`s used by serialization system. This should improve performance somewhat.
-
-### Internal
-
-* Avoided sorting overlays every render frame.
-* Various clean up to grid fixture code/adding asserts.
-
-## 239.0.1
-
-### Bugfixes
-
-* Fix logging of received packets with `net.packet` logging level.
-* Downgrade `VorbisPizza` to fix audio playback for systems without AVX2 support.
-
-### Other
-
-* Improved performance of some Roslyn analyzers and source generators, which should significantly improve compile times and IDE performance.
-
-
-## 239.0.0
-
-### Breaking changes
-
-* Robust now uses **.NET 9**.
-* `ISerializationManager` will now log errors if it encounters `Entity<T>` data-fields.
-  * To be clear, this has never been supported and is not really a breaking change, but this will likely require manual intervention to prevent tests from failing.
-* `IClyde.TextInputSetRect`, `TextInputStart` and `TextInputStop` have been moved to be on `IClydeWindow`.
-* Updated various NuGet dependencies and removed some other ones, of note:
-  * `FastAccessors`, which is a transitive dep we never used, is now gone. It might have snuck into some `using` statement thanks to your IDE, and those will now fail to compile. Remove them.
-  * NUnit `Is.EqualTo(default)` seems to have ambiguous overload resolution in some cases now, this can be fixed by using an explicit `default(type)` syntax.
-  * This also fixed various false-positive warnings reported by NuGet.
-
-### New features
-
-* Added `MockInterfaces.MakeConfigurationManager` for creating functional configuration managers for unit test mocking.
-* Added `ISawmill.IsLogLevelEnabled()` to avoid doing expensive verbose logging operations when not necessary.
-* ``string[] Split(System.ReadOnlySpan`1<char>)`` is now available in sandbox.
-
-### Bugfixes
-
-* Fixed auto-generated component delta-states not raising `AfterAutoHandleStateEvent`
-* Fixed auto-generated component delta-states improperly implementing `IComponentDeltaState` methods. May have caused bugs in replays.
-* Fixed `Robust.Client.WebView` on the launcher via a new release.
-* Fixed an exception that could occur when saving a map that had tiles migrated by alias.
-
-### Other
-
-* The `loglevel` command now properly shows the "`null`" log level that resets the level to inheriting from parent. This was already supported by it, but the completions didn't list it.
-
-### Internal
-
-* Experimental SDL2 windowing backend has been replaced with SDL3. SDL3 backend is also more feature-complete, though it is still not in use.
-* Updated CEF used by Robust.Client.WebView to 131.3.5.
-
-## 238.0.1
-
-### Bugfixes
-
-* Fixed source generation for auto-networked EntityUid Dictionaries missing a semicolon
-* Fixed PlacementManager using the wrong coordinates when deleting entities in an area.
-
-
-## 238.0.0
-
-### Breaking changes
-
-* Some toolshed command syntax/parsing has changed slightly, and several toolshed related classes and interfaces have changed significantly, including ToolshedManager, type parsers, invocation contexts, and parser contexts. For more detail see the the description of PR #5455
-
-
-## 237.4.0
-
-### New features
-
-* Implement automatic field-level delta states via AutoGenerateComponentState via opt-in.
-
-### Bugfixes
-
-* Remove redundant TransformComponentState bool.
-
-
-## 237.3.0
-
-### New features
-
-* Added stack-like functions to `ValueList<T>` and added an `AddRange(ReadOnlySpan<T>)` overload.
-* Added new `AssetPassFilterDrop`.
-* Added a new RayCastSystem with the latest Box2D raycast + shapecasts implemented.
-
-### Bugfixes
-
-* Fixed `IPrototypeManager.TryGetKindFrom()` not working for prototypes with automatically inferred kind names.
-
-### Other
-
-* Sandbox error reference locator now works with generic method calls.
